Description

This gel goes beyond the traditional role of sports nutrition by incorporating a nootropic to assist with attention, focus, and cognitive clarity. When the pressure builds during long training sessions or races, staying mentally switched on is just as important as fuelling your muscles. Cognizin® Citicoline helps support brain function by enhancing neurotransmitter activity, giving you that extra mental edge when it matters most.

With an isotonic formulation, the Beta Fuel + Nootropics Gel is easy to consume and rapidly absorbed, no water needed. It fits seamlessly into a broader fuelling strategy that includes Beta Fuel drinks and chews, ensuring you're fully supported no matter the demands of your sport. Developed with elite athletes and backed by science, this gel reflects SiS's commitment to innovation and performance.

If you’re aiming to unlock your full endurance potential, physically and mentally, this is the product that bridges the gap between body and brain. It's ideal for marathons, long-distance cycling, triathlons, and ultra events where consistent fuelling and sharp decision-making are crucial.

How does it work

The SiS Beta Fuel + Nootropics Energy Gel combines two key elements: energy and cognition. The dual-source carbohydrate blend (maltodextrin and fructose in a 1:0.8 ratio) is designed to deliver up to 40g of fast-absorbing energy per gel, allowing athletes to meet the recommended 80–120g of carbs per hour without upsetting the stomach. This helps maintain power output and delay fatigue during extended periods of physical exertion.

Alongside this, the inclusion of Cognizin® Citicoline, an evidence-backed nootropic, supports mental performance by enhancing acetylcholine production, a neurotransmitter vital for attention, memory and mental clarity. The isotonic nature of the gel allows for rapid absorption of both the carbohydrates and nootropic compounds, making it an ideal solution to support both body and mind in high-demand scenarios.
